Description

The present invention relates to a pulling tool for pulling out an aerosol-generating article received in an aerosol generator. The present invention further relates to a mouthpiece comprising an aerosol generator and such a extraction tool.

Numerous prior art literature discloses, for example, aerosol generators including heated aerosol generators and electrically heated aerosol generators. One advantage of these systems is that smokers can selectively suspend and resume aerosol generation while significantly reducing sidestream smoke. An example of a heated aerosol generation system is disclosed in US Pat. No. 5,144,962, which, in one embodiment, comprises a flavor generating medium in contact with a heater. When the medium is depleted, both the medium and the heater are replaced. An aerosol generator that can replace the substrate without the need to remove the heating element is desirable.

WO2013 / 076098 and WO2016 / 124550 disclose an aerosol generator having a heater that can be inserted into an aerosol-forming substrate of an aerosol-generating article, and a extraction tool that facilitates removal of the aerosol-generating article after use. Such disclosure describes a remover having a stopper protruding from the outside of the remover. The stopper is arranged to cooperate with a recess located in the sleeve located in the aerosol generator, thereby coupling the extractor to the aerosol generator. However, this engagement mechanism, that is, the cooperation between the recess and the protrusion stopper, is not always reliable and can deteriorate over time. This causes difficulty in removing, attaching and detaching, and reattaching the extractor, and can also affect the stability and usability of the device. Therefore, it is desirable to provide an improved extraction tool for facilitating the removal of aerosol-generating articles that does not suffer from such problems.

According to the first aspect of the present invention, there is provided a extraction tool for extracting an aerosol-generating article received in the aerosol generator. The extraction tool comprises a body defining a recess for receiving the aerosol-generating article and an elastic coupling element attached to the body of the extraction tool. The elastic coupling element is movable with respect to the body of the extractor and detachably couples the extractor to a portion of the aerosol generator. It is preferred that the elastic coupling element be movable independently of the body of the extraction tool and that the extraction tool is removably coupled to a portion of the aerosol generator.

The term "removably coupled" is configured such that the body of the extractor is coupled to that portion of the aerosol generator so that the extractor is coupled to a portion of the aerosol generator in a substantially immovable manner. And, so that the body of the extractor can move with respect to a part of the aerosol generator, the body of the extractor is configured to be free from being immovably coupled to that part of the aerosol generator. Means to be done.

The features described in the following preferred embodiments may be provided in any aspect of the invention and in any suitable combination.

By providing an elastic coupling element that is attached to the body of the extractor and arranging the element so that it can be moved independently of the body of the extractor, the extractor can deform the body of the extractor. Instead, it can be repeatedly attached to and removed from the rest of the aerosol generator. This is because only the elastic coupling element moves or deforms as the extractor engages and disengages with the rest of the aerosol generator. This has the advantage that the body of the extractor has a longer life and the elastic coupling element can be designed specifically to accommodate these repeated deformations so that it is not subject to excessive repeated deformations. means. Further, if the extraction tool body is not repeatedly deformed during use of the aerosol generator, it may be possible to obtain a more consistent aerosol delivery from smoke absorption.

It must undergo repeated deformations when its body is removed from the device and inserted into the device, thereby causing such repeated deformations and potential degradation, and possible deterioration. This is in contrast to conventional extractors, which affect the material life of the extractor body due to complete breakage of the extractor body. Such deterioration can also affect the performance of the extractor. That is, deterioration can adversely affect the ability of the extractor to be attached to the repeater. This can adversely affect the user experience of the device.

As used herein, "aerosol generator" refers to an apparatus that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol-forming substrate may be part of the aerosol-generating article. The aerosol generator may include one or more components used to supply energy from a power source to the aerosol forming substrate to generate the aerosol. For example, the aerosol generator may be a heated aerosol generator. The aerosol generator may be an electrically heated aerosol generator or a gas heated aerosol generator. The aerosol generator may be an aerosol generator that interacts with an aerosol-forming substrate of an aerosol-generating article to generate an aerosol that can be inhaled directly into the user's lungs through the user's mouth. The aerosol generator may be a holder.

As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate capable of releasing volatile compounds capable of forming an aerosol. For example, the aerosol-generating article may be an aerosol-generating article that produces an aerosol that can be inhaled directly into the user's lungs through the user's mouth. Aerosol-generating articles may be disposable. From now on, the term "aerosol-generating article" will be commonly used.

As used herein, the term "aerosol-forming substrate" refers to a substrate capable of releasing volatile compounds capable of forming an aerosol. These volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may conveniently be a portion of the aerosol-generating article or an aerosol-generating article.

The aerosol-generating article is preferably a heated aerosol-generating article, which is an aerosol-generating article containing an aerosol-forming substrate intended to be heated rather than burned in order to release a volatile compound capable of forming an aerosol. .. The aerosol formed by heating the aerosol-forming substrate may contain less known harmful components than produced by combustion or thermal decomposition of the aerosol-forming substrate. Aerosol-generating articles may or may be tobacco sticks.

The extraction tool body is preferably designed to be suitable for receiving aerosol-generating articles. This means that the indentation defined by the extraction tool body substantially corresponds to the shape or profile of the aerosol-generating article configured to receive the indentation.

The extraction tool body is trapped or held within the extraction tool portion of the aerosol generator when the aerosol-generating article is extracted, particles of the aerosol-forming substrate, or other debris that may be derived from the aerosol-generating article. It is preferable that it is designed as such. Thus, the extractor can be periodically removed from the device and cleaned to maintain the consumer experience.

The invention further makes it possible to substantially maintain the integrity of the aerosol-generating article when it is removed from the aerosol generator. The risk of loosening of fragments of the aerosol-forming substrate from the aerosol-generating article during removal and retention in the aerosol generator is significantly reduced. This is advantageous because the aerosol generator does not need to be cleaned frequently.

The body of the extractor preferably has a first end defining an opening in the recess and a second end opposite, with at least the first portion of the elastic coupling element being the first to the first. It extends in the direction of the second end. The first portion of the elastic coupling element may be elongated. The provision of the opening allows the aerosol-generating article to be received in the extraction tool through the first end.

The distance between the opposite first and second ends of the extraction tool body defines the length of the extraction tool or the extraction tool body in the longitudinal direction.

It is preferred that the body of the extraction tool may include a surface to which the aerosol-generating article comes into contact when the aerosol-forming substrate of the aerosol-generating article is accurately positioned within the extraction tool. This indicates to the user that the aerosol-generating article has been completely inserted into the extraction tool body. This reduces the potential for damage to the aerosol-forming substrate during insertion.

It is preferred that the first end is the open end and the second end is substantially the closed end. The second substantially closed end may form an end support surface that can provide a support or seat for the aerosol-generating article received within the scavenger. Alternatively, both the first and second ends are open ends, and the support surface for providing a support or seat for aerosol-generating articles is the first open end and the second. Located in the extractor at a position between the open end. It is preferable that the aerosol-generating article substantially abuts on the support surface.

Orienting the elastic coupling element in this way allows the extraction tool to be effectively reattached and detached without adding excessive deformation to the elastic coupling element. This is because it is preferable that the second end on the opposite side of the extraction tool body faces the aerosol generator when the extraction tool is connected to the device. Therefore, it is preferred that the first portion of the elastic coupling element extends in the same direction as the moving direction required to detachably bond the body of the extractor to the aerosol generator or a portion thereof. In addition, the first portion of the elastic coupling element is subjected to minimal outward bending force, especially when the user removes the extractor by pulling from the aerosol generator.

Alternatively, the first portion of the elastic coupling element may be oriented in the opposite direction. In other words, at least the first portion of the elastic coupling element may extend from the first end to the second end.

The first portion of the elastic coupling element may not extend past either the first or second end of the body. Alternatively, the first portion of the elastic coupling element may extend through either the first or second end of the body.

The extraction tool body may further define an airflow channel to allow air to flow into the depression. Upon use, the user can inhale the edges of the aerosol-generating article received in the indentation. The aerosol-generating article comprises an aerosol-forming substrate that is heated by a heater. Air is sucked into the recess through the airflow channel and flows over the aerosol-forming substrate. Volatile components generated from the heated aerosol-forming substrate are mixed into the air stream and condensed to form an inhalable aerosol.

The first part of the elastic coupling element can extend from the proximal end of the first part attached to the body of the extractor to the distal end of the first part through the gap from the body of the extractor. preferable.

The proximal end of the first portion of the elastic coupling element can be attached at any point along the body of the extractor. In some embodiments, the proximal end of the first portion of the elastic coupling element is along the body of the extractor, the first end of the body of the extractor and the length of the body of the extractor. Attached between points.

The distal end of the first portion of the elastic coupling element is located between the first and second ends of the stripper body. Alternatively, the distal end of the first portion of the elastic coupling element is at the first or second end of the extraction tool body so that the elastic coupling element extends outward of the extraction tool body. It may be located at a position that has passed any of them.

The first portion of the elastic coupling element can have any suitable length. The length of the first portion of the elastic coupling element is preferably shorter than the length of the extraction tool body. In some preferred embodiments, the length of the first portion of the elastic coupling element is from about 25% to about 75% of the length of the stripper body. Such lengths advantageously allow the elastic coupling element to be included as part of the puller without increasing or significantly increasing the footprint of the puller. These lengths also make it possible to allow the elastic coupling element to be displaced sufficiently to detachably bond the extractor to the aerosol generator.

The elastic coupling element preferably further comprises a second portion, the second portion being the first end attached to the body of the extractor and the second end disposed away from the body of the extractor. Has.

The first and second parts of the elastic coupling element may be joined together. In particular, the second end of the second part may be joined to the proximal end of the first part of the elastic coupling element, or to any other position along the first part. good. In these embodiments, the first and second parts of the elastic coupling element may be integrally formed together.

The overhang is preferably provided on the first portion of the elastic coupling element, the overhang extending away from the body of the extractor.

The protrusion may be configured to removably engage a portion of the aerosol generator. A portion of the aerosol generator may be a casing containing one or more openings or recesses to receive the protrusions of the elastic coupling element. The portion of the aerosol generator is any suitable portion suitable for receiving the extraction tool and has suitable means for receiving or cooperating with the protrusions of the elastic coupling element.

The protrusion preferably has a first inclined surface oriented towards the first end of the extraction tool body and a second inclined surface oriented towards the second end of the extraction tool body.

It is preferable that the second inclined surface is inclined more gently than the first inclined surface.

The protrusions are any other suitable protrusions configured to be received or snapped to by cam-shaped elements, lugs, angled or bent parts, hooks, studs, beads, or openings or dents. Can contain elements. For example, in some preferred embodiments, the first portion of the elastic coupling element may include a bent portion on which a first tilted surface and a second tilted surface are formed.

The first sloping surface of the protrusion is an elastic coupling element towards the scavenger body as the scavenger is inserted into a portion of the aerosol generator to allow the scavenger to be coupled to that portion of the device. It can be configured to allow deviation or movement. In other words, as the first inclined surface slides against the edge of a portion of the aerosol generator, the sliding movement of the extractor within the portion of the aerosol generator directs the elastic coupling element towards the body of the extractor. And press. The degree of inclination of the first inclined surface determines the amount of force required to deflect the elastic coupling element towards the extraction tool body when the extraction tool is inserted into a portion of the aerosol generator. The steeper the first slope, the greater the force required to deviate the elastic coupling element. The degree of inclination of the second inclined surface is required to deflect the elastic coupling element towards the extraction tool body when the extraction tool is released from engagement with an opening or recess in a portion of the aerosol generator. Determine the amount of force. The steeper the second slope, the greater the amount of force required to deviate the elastic coupling element when pulling the protrusion out of engagement with an opening or recess in a portion of the aerosol generator. Therefore, the force required to engage or disengage, or combine or disengage a portion of the extraction tool from the aerosol generator is the shape of the protrusion and the inclination of its first and second inclined surfaces. It depends substantially on the degree.

Thus, the first and second sloping surfaces of the elastic coupling element are required to detachably bond the scavenger to a portion of the aerosol generator and to separate the scavenger from a portion of the aerosol generator, respectively. Determine the amount of force. The second inclined surface is preferably more gently inclined than the first inclined surface so that it is more difficult for the user to accidentally separate the extraction tool during the use of the aerosol generator. If the first part of the elastic coupling element is oriented in the opposite direction, in other words, if the first portion of the elastic coupling element extends from the first end to the second end, the first inclined surface Is preferably more gently inclined than the second inclined surface.

The protrusion is preferably provided at the proximal or distal end of the first portion of the elastic coupling element. Alternatively, the protrusion may be provided at any position along the first portion of the elastic coupling element.

The elastic coupling element is preferably swivelable or bendable with respect to the body of the extractor. The elastic coupling element is preferably configured to be swiveled or bent independently of the body of the extractor. The elastic coupling element preferably comprises a cantilever element that can be displaced or bent. As mentioned above, the elastic coupling element can be moved with respect to the extraction tool or independently of the extraction tool body, from the elastic coupling element to the main body when the elastic coupling element is displaced or bent with respect to the main body. Ensure that minimal force is transmitted or is not transmitted. For this reason, the elastic coupling element may be made of a plastic material, taking into account the high level of flexibility of the plastic material. Other materials such as metal may also be suitable.

It is preferred that the elastic coupling element can be urged towards the urging position. The elastic coupling element can be a spring-loaded device or element. The elastic coupling element can be an elastic protruding element configured to snap fit and engage with a portion of the aerosol generator. Such elastic protrusions can be cantilever, girder, or beam. A swivel point or hinge may be provided on the stripper body so that the elastic coupling element can be moved towards and away from the stripper body. If the elastic coupling element comprises a first part and a second part, a pivot point or hinge may be provided at the intersection between the first part and the second part.

The elastic coupling element preferably includes an extension in the longitudinal direction and is attached to the extraction tool body so as to have one end attached to the extraction tool body and a remote end via a gap from the extraction tool body. ..

The elastic coupling element is preferably separable from the body of the extractor. This is advantageous because it allows the elastic coupling element to be replaced in the event of breakage during use, without the need to replace the entire extraction tool body with the integral coupling element. Replacing the elastic coupling element can be cheaper than replacing the entire strip. This is because the elastic coupling element may not be integrated with the extraction tool body. Moreover, the inclusion of elastic coupling elements according to the present invention does not significantly affect the manufacture of the extraction tool or aerosol generator.

The extractor preferably comprises one or more additional elastic coupling elements, each of which is attached to the body of the extraction tool, and each of the additional elastic coupling elements is a extraction tool. Movable with respect to the body of the scavenger and detachably coupled to a portion of the aerosol generator. The extractor preferably further comprises one or more additional elastic coupling elements, each of which is attached to the body of the extraction tool, and each of the additional elastic coupling elements is extracted. It is movable independently of the body of the tool and detachably couples the extractor to a portion of the aerosol generator.

For example, if the extraction tool body has a substantially circular cross section, the elastic coupling elements may have gaps at equal intervals around the outer circumference of the extraction tool body.

Each of the additional elastic coupling elements may have any combination of the features described above with respect to the elastic coupling elements.

According to the second aspect of the present invention, there is provided an aerosol generator capable of receiving an aerosol generating article. The device comprises a heater casing or sleeve containing a heater for heating the aerosol-generating article and a remover according to the first aspect of the invention, the elastic coupling element allowing the remover to be removed from the heater casing or sleeve. It is configured to bind to.

The aerosol generator includes a heater casing for receiving the extractor so that the extractor slides into the heater casing. The heater casing preferably forms part of the housing of the aerosol generator. Alternatively, the heater casing may include a separate component configured to be coupled to the aerosol generator.

The heater casing may include a tube having at least one open end for receiving the extraction tool and an aerosol generating article received within the extraction tool. The extraction tool body has a substantially cylindrical shape and forms a sliding receptacle having a diameter slightly smaller than the diameter of the heater casing so that the extraction tool body can be substantially received in the heater casing. do. The extractor body may include a flange arranged to abut the end of the heater casing when the extractor body is fully connected to the heater casing.

The heater casing may further provide a projecting guide track extending in the longitudinal direction along the inner surface of the heater casing. The guide track is arranged to cooperate with a slot or groove located along the outer surface of the extraction tool body. The engagement of the guide track with the corresponding slot on the extractor body ensures that the extractor body does not rotate when located in the heater casing or slides. Alternatively, the heater casing may further provide a guide slot, and the extractor body may provide a guide slot for the heater casing so that the extractor body does not rotate when positioned or slid within the heater casing. May have protrusions configured to work with.

The heater casing further provides a container in which the heater is substantially housed. This can reduce the possibility of the user coming into direct contact with the heater of the device.

The term "electric heater" means one or more electric heating elements. The electric heater may include an internal electric heating element for at least partially inserting the aerosol-generating article into the aerosol-forming substrate when the aerosol-generating article is received in the extraction tool and the extraction tool is close to the heater. An "internal heating element" is suitable for insertion or penetration into an aerosol-generating material. The present invention is particularly advantageous when used with an internal heating element, which tends to cause the aerosol-forming substrate to stick to the heating element and thus disintegrate when the aerosol-forming substrate is separated from the heating element. This is to get rid of.

Alternatively or additionally, the electric heater may be equipped with an external heating element. The term "external heating element" means one that at least partially encloses an aerosol-forming substrate. The electric heater may include one or more internal heating elements and one or more external heating elements.

The electric heater may include a single heating element. Alternatively, the electric heater may include one or more heating elements. The heating element (s) may be appropriately disposed to heat the aerosol-forming substrate most effectively.

Other alternatives include heating wires or filaments such as Ni-Cr (nickel chromium), platinum, tungsten, or alloy wires or heating plates. Optionally, the heating element may be placed in or on a rigid carrier material.

The electric heater may include a heat sink or a heat storage body that includes a material capable of absorbing and storing heat and then releasing heat to an aerosol-forming substrate over a period of time. The heat sink may be made of any suitable material, such as a suitable metal or ceramic material. In one embodiment, the material is a material that has a high heat capacity (a heat storage material suitable for the purpose) or is capable of absorbing heat and then releasing it through a reversible process (such as a high temperature phase change). be. Suitable heat storage materials for the purpose include silica gel, alumina, carbon, glass mats, fiberglass, minerals, metals or alloys (aluminum, silver or lead), and cellulosic materials (such as paper). Other suitable materials that release heat through reversible phase changes include paraffins, sodium acetate, naphthalin, waxes, polyethylene oxides, metals, metal salts, mixtures or alloys of eutectic salts.

The heat sink or heat storage body may be arranged so as to be in direct contact with the aerosol-forming substrate and to transfer the stored heat directly to the substrate. Alternatively, the heat stored in the heat sink or heat storage can be transferred to the aerosol forming substrate by means of a heat conductor such as a metal tube.

The electric heater can heat the aerosol-forming substrate by conduction. The electric heater may be at least partially in contact with the substrate or the carrier to which the substrate is attached. Alternatively, the heat from the electric heater can be conducted to the substrate by means of a heat conductive element.

Alternatively, the electric heater may transfer heat to the incoming ambient air drawn through a heated aerosol generation system during use, which in turn heats the aerosol-forming substrate by convection. The ambient air may be heated before passing through the aerosol-forming substrate.

The device preferably includes a mouthpiece. The mouthpiece is formed by a mouthpiece housing and a pull-out tool located within the mouthpiece housing. The mouthpiece is preferably a separable and replaceable component of the aerosol generator. It is called a mouthpiece because it is located at the oral or downstream end of the device. The mouthpiece refers to a portion of the housing of the aerosol generator and is preferably located at the end of the device. During use, the aerosol-generating article containing the aerosol-forming substrate is preferably partially contained within the mouthpiece of the aerosol generator. During use, the user does not smoke the mouthpiece or mouthpiece housing directly, but smokes the aerosol-generating article extending from it. As a result, the mouthpiece is believed to form the most downstream portion of the aerosol generator, thus the portion of the device is positioned closest to the user's mouth during use. Advantageously, the mouthpiece may be manufactured and sold separately, providing the user with a selection of personalization of devices with different mouthpieces with different technical and / or aesthetic functions or features.

The extraction tool body is preferably fixedly coupled to the mouthpiece so that the extraction tool body does not move with respect to the mouthpiece or the mouthpiece housing.

The effective diameter of the extractor, which is the diameter of the body plus the radial distance of the elastic coupling element extending from the extractor body, shall be less than the diameter of at least a portion of the mouthpiece housing that houses the extractor. Is preferable. In addition, the mouthpiece housing should also be sized to receive at least a portion of the aerosol-generating article. There should be a gap between the mouthpiece housing and the extraction tool in the mouthpiece housing so that the heater casing can slide into the mouthpiece housing and the extraction tool is inside the heater casing. ..

The heater is preferably configured to extend in the longitudinal direction with respect to the device and penetrate the inner portion of the aerosol generating article. The heater preferably projects in the long axis direction. For example, the heating element may be in the form of a heater blade that heats the aerosol-generating substrate of the aerosol-generating article received in the extraction tool from the inside. In addition, protruding or extending heaters are easier to clean after use and are easier to replace in case of damage or wear.

The end of the body of the extraction tool preferably includes an opening to allow the heater to be received within the recess of the extraction tool. The opening is preferably provided on the second end of the scavenger. It is preferred that the second end of the extraction tool provides a surface with which the aerosol generating article abuts, thereby supporting the article within the extraction tool.

The main body of the extraction tool is preferably configured to slide in the heater casing of the aerosol generator. The body of the extractor may include a sliding receptacle for receiving the aerosol-generating article, which is slidable within the heater casing. The terms "retractor body" or "retractor body" may be used interchangeably throughout the specification with the terms "sliding receptacle" or "sliding receptacle".

When the extractor is coupled to the heater casing, the extractor is preferably configured to move between a first position and a second position. The first position is the operating position where the heater extends into the recess of the extraction tool body, and the second position is the extraction position where at least part of the heater is removed from the recess.

As mentioned above, the body of the extractor may include a sliding receptacle for receiving the aerosol-generating article. Therefore, the sliding receptacle is slidable between the first and second positions. The entire mouthpiece, including the sliding receptacle, may be moved to translate the sliding receptacle between the first and second positions. Alternatively, the sliding receptacle of the extractor may be slidable between the first and second positions.

The extractor is preferably left attached to the aerosol generator or heater casing when the extractor is in the first and second positions. The extractor is also more preferably left attached to the aerosol generator when the extractor is located between the first and second positions.

The first position of the sliding receptacle is the operating position where the heater can heat the aerosol-forming substrate of the aerosol-generating article to form the aerosol. As is well known to those skilled in the art, aerosols are solid particles or liquid droplets, or both solid particles and liquid droplets suspended in a gas such as air. The second position of the sliding receptacle is a sampling position that facilitates removal of the aerosol-generating article from the aerosol generator by the user or consumer. The upstream and downstream ends of the aerosol generator are defined with respect to the airflow as the user inhales. Normally, the incoming air enters the aerosol generator at the upstream end, is mixed with the aerosol, and the aerosol is carried into the airflow towards the user's mouth at the downstream end.

The aerosol-generating article containing the aerosol-forming substrate is preferably provided to the aerosol generator. In this embodiment, the aerosol-generating article remains substantially stationary with respect to the sliding receptacle as the sliding receptacle slides between the first and second positions. The term "substantially stationary" is defined as a change in position in millimeters during the use of an aerosol generator. The receptacle or extractor body and aerosol generator move with respect to other components of the aerosol generator, including the heater and heater casing. This makes it possible to achieve the removal of the aerosol-generating article from the aerosol generator in two stages. In the first stage, the aerosol-generating article and the sliding receptacle move by sliding, while the aerosol-forming substrate is supported by the components of the aerosol generator, specifically the heater. In the second step, the aerosol-generating article separated from the heater can be removed from the sliding receptacle.

The heater casing preferably comprises a first coupling recess or opening and a second coupling recess or opening, and when the extractor is in the first position, at least a portion of the elastic coupling element is the first coupling recess or opening.

The portion of the elastic coupling element that engages the coupling recess or opening is preferably a protrusion of the elastic coupling element.

The heater casing preferably contains one or more openings or recesses to receive the protrusions of the elastic coupling element. Advantageously, the engagement of the elastic coupling element with either the first or second coupling recess or opening provides a safe and stable removable coupling of the extractor. This can prevent the heated aerosol-generating article from unintentionally escaping from the device. In addition, such an arrangement may allow snap-fit engagement between the device and the extractor. This provides easy coupling and separation of the extractor to the aerosol generator, as well as reliable tactile and audible feedback that the extractor has locked or engaged in either the first or second position. Can be made possible.

It is preferred that the first coupling recess or opening is provided further away from the open end of the heater casing than the second coupling recess or opening. It is preferred that the second coupling recess or opening be provided closer to the open end of the heater casing than the first coupling recess or opening.

The heater casing preferably contains a pair of recesses or openings corresponding to each of the elastic coupling elements provided on the extractor. For example, if two elastic coupling elements are provided on the stripper body, the heater casing may contain two pairs of first and second coupling recesses or openings corresponding to each of the two elastic coupling elements. preferable. When the heater casing has a substantially circular cross section, each pair of first and second coupling recesses or openings corresponding to each of the two elastic coupling elements is evenly spaced around the outer circumference of the heater casing. sell.

At least a portion of the elastic coupling element is preferably configured to be frictionally engaged with the inner surface of the heater casing as the extractor moves between the first and second positions. Such frictional engagement can provide an improved and more stable sensation to the user when moving the extractor between the first and second positions. In particular, such frictional engagement means that the extractor does not move freely between the first and second positions and instead requires user input. This means that the extractor only moves between positions when the user applies a moving force and therefore does not move unintentionally (eg, due to gravity) between the positions. sell.

According to a third aspect of the present invention, a mouthpiece for an aerosol generator is provided. The mouthpiece comprises a mouthpiece housing and a pull-out tool according to the first aspect of the present invention, and the pull-out tool is arranged in the mouthpiece housing.

As used herein, the term "homogenized tobacco material" includes any tobacco material formed by the agglomeration of particles of the tobacco material. A sheet or web of homogenized tobacco material agglomerates particulate tobacco obtained by grinding one or both of the tobacco leaf lamina and tobacco leaf stem, or by powdering in another way. Formed by In addition, the homogenized tobacco material may contain one or more of the small amounts of tobacco dust, tobacco fines, and other particulate tobacco by-products formed during tobacco processing, handling, and shipping. Sheets of homogenized tobacco material may be produced by casting, extrusion, papermaking processes, or any other suitable process well known in the art.

The rod may include one or more sheets of homogenized tobacco material that are collected to form a plug and surrounded by an outer wrapper. The term "sheet" as used herein with respect to the present invention describes a thin layered element having a width and length significantly greater than its thickness.

FIG. 8 shows a perspective view of the heater casing of the aerosol generator. FIG. 9 shows a front elevation view of the mouthpiece according to the present invention.

FIG. 1 shows a mouthpiece 1 according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the mouthpiece 1 includes a extraction tool 10 for receiving an aerosol-generating article (not shown) and a mouthpiece housing 30 for accommodating the extraction tool 10. The mouthpiece 1 is configured to be attached to a downstream portion of an aerosol generator (not shown). Such downstream portions are, in the present invention, removablely coupled to an aerosol generator and configured to accommodate a heater (not shown) of the device, the heater casings shown in FIGS. 1, 2 and 8. It is 50. Although the heater casing 50 is shown as a separate component from the aerosol generator, the heater casing 50 can be formed integrally with the device.

As shown in FIGS. 1, 2, 3a and 3b, the extraction tool body 20 defines a recess for receiving the aerosol-generating article. As shown in FIG. 1, the body 20 includes a second end 22 on the opposite side of the first end 21, the first end 21 being open, thereby providing an inlet or an entrance to the recess of the body 20. It defines an opening and the second end 22 is substantially closed, thereby providing a support surface for abutting the aerosol-generating article when the article is received within the extraction tool 10. ..

The extraction tool 10 is configured to be fixedly mounted in the housing 30 of the mouthpiece 1. As shown in FIG. 1, the mouthpiece housing 30 has an open end 31 for receiving an aerosol-generating article. Inserting the aerosol-generating article into the mouthpiece 1 involves inserting the aerosol-generating article through the open end 31 into the recess defined by the extraction tool body 20. It is considered that the aerosol-generating article was completely inserted into the mouthpiece 1 when the aerosol-forming substrate end of the aerosol-generating article came into contact with the closed end 22 which is the second inner surface. Since the extraction tool 10 is fixedly attached to the mouthpiece housing 30, the extraction tool 10 does not move with respect to the mouthpiece housing 30 or the mouthpiece 1.

As shown in FIGS. 1, 2, 3a and 3b, both the extraction tool body 20 and the heater casing 50 include a substantially cylindrical tube. The diameter of the extraction tool main body 20 is slightly smaller than the diameter of the heater casing 50 so that the extraction tool main body 20 can slide or move in the heater casing 50. The diameter of the extraction tool body 20 is also smaller than the diameter of the upstream single of the mouthpiece housing 30 so that the extraction tool 10 can be substantially accommodated in the mouthpiece housing 30. However, sufficient clearance is provided between the extractor 10 and the inner surface of the mouthpiece to allow the extractor 10 to slide into and within the heater casing 50. Need to be done. These gaps also allow air to flow into the extraction tool 10 and, through the aerosol-forming substrate, carry the aerosol formed during heating to the user downstream of the mouthpiece 1.

During use, the heater casing 50 is substantially housed within the mouthpiece housing 30. This is advantageous because it prevents the user from coming into direct contact with the heater casing 50 during use. The mouthpiece housing 30 and the heater casing 50 also provide insulation from the heater, as the heater casing 50 may become too hot for the user to touch during use.

The heater (not shown) is supported on the inner surface of the heater casing 50. As shown in FIGS. 1 and 2, the heater casing 50 has an open end 51 for receiving the aerosol-generating article located within the extraction tool 10, and thus the aerosol-generating article, so that the aerosol-generating article can be heated by the heater. include. The heater (not shown) includes a heating element extending in the long axis direction. The closed end 22 of the extraction tool body 20 includes an opening 26 shown in FIG. 3a, through which the heater is configured to extend into a recess defined by the extraction tool body 20.

As shown in FIGS. 3a and 3b, the closed end 22 further includes a flange 23 in the form of a protruding rim or collar, which abuts on the inner surface of the casing 50 that supports the protruding heater. The extraction tool body 20 also includes an alignment lug 24 that ensures that the body 20 is fitted and attached to the mouthpiece housing 30 in the correct orientation. The alignment lug 24 cooperates with a corresponding recess (not shown) located inside the mouthpiece housing 30. Correctly orienting the extraction tool body 20 also means that the opening 26 can be accurately aligned with the heater as the extraction tool 10 moves within the heater casing 50.

The extractor 10 further includes two elastic coupling elements 25 attached to the outer surface of the extractor body 20 as illustrated in FIGS. 2 and 3b. The elastic coupling element 25 is configured to be bendable or movable independently of the main body 20 when the extraction tool 10 is inserted into the open end 51 of the heater casing 50. As shown in FIGS. 2 and 3b, the elastic coupling element 25 includes an elastic cantilever or clip formed by a first portion 251 and a second portion 252 that are integrally joined together. The first portion 251 substantially extends from the open end 21 of the extraction tool body 20 along the direction of the closed end 22 of the extraction tool body 20. Therefore, the first portion 251 is close to the open end 21 and has a gap from the proximal end attached to the body 20 via the second portion 252, close to the closed end 22 and away from the body 20. It extends to the distal end through. The second portion 252 extends from the first end attached to the body 20 to the second end joined to the proximal end of the first portion 251 of the elastic coupling element. Therefore, there is a gap between the first portion 251 of the elastic coupling element 25 and the main body 20 of the extraction tool 10, and when the elastic coupling element is deformed when sliding in the heater casing 50, the elastic coupling element is directed toward it. Allows space for folding.

As shown in FIGS. 2 and 3b, the elastic coupling element 25 includes a protrusion 253 provided on the distal end of the first portion 251 of each elastic coupling element 25. The protrusion 253 extends away from the body 20 and is arranged to collaboratively engage with the coupling opening 55 located along the heater casing 50. As shown in FIG. 2, the protruding portion 253 is in the form of a protruding bent portion of the elastic coupling element 25.

The elastic coupling element 25 has a protrusion 253 so that there is a gap between the first portion 251 of the elastic coupling element 25 and the extraction tool main body 20 in a state where the elastic coupling element 25 is not deformed or displaced. Is urged and arranged so as to be separated from the main body 20 of the extraction tool 10. In the displaced state, the first portion 251 is bent toward the main body 20 of the extraction tool 10 as shown in FIG. 7b. Therefore, the effective diameter of the extraction tool 10, that is, the diameter of the extraction tool 10 when the elastic coupling element 25 (see FIG. 7a) attached to the main body 20 of the extraction tool 10 in a non-shifted state is taken into consideration, is the diameter of the extraction tool 10. The elastic coupling element 25 is larger than the effective diameter of the extraction tool 10 in the displaced state (see FIGS. 7a and 7c).

As shown in FIG. 8, the heater casing 50 includes two pairs of coupling openings 55, each of which is arranged to receive the respective protrusion 253 of the elastic coupling element 25. Each pair of coupling openings 55 is located at a different outer peripheral position on the heater casing 50, and each pair of coupling openings 55 includes a first coupling opening 551 and a second coupling opening 552.

The first coupling opening 551 heaters the extraction tool 10 at a first operating position where the heater of the aerosol generator can heat the aerosol-forming substrate of the aerosol-generating article located within the mouthpiece 1 and the extraction tool 10. It is arranged so as to be detachably coupled to the casing 50. In the first position, the heater extends through the opening 26 and penetrates the interior of the aerosol-forming substrate to heat and form an inhalable aerosol for the user to smoke.

The second coupling opening 552 is at least removed from the aerosol-forming substrate of the aerosol-generating article located within the mouthpiece 1 and the extraction tool 10 so that the heater of the aerosol generator is facilitated removal of the article from the extraction tool 10. At the second extraction position, the extraction tool 10 is arranged so as to be detachably coupled to the heater casing 50. In the second position, the heater penetrates the aerosol-forming substrate less than in the first operating position, or does not penetrate the aerosol-forming substrate at all.

As a result of the respective purposes of the coupling openings 551 and 552, the first coupling opening 551 is arranged further away from the open end 51 of the heater casing 50 than the second coupling opening 552.

During use, the user inserts the aerosol-generating article into the mouthpiece 1 when the extractor 10 is in the first position so that the heater penetrates the interior of the aerosol-generating article (as shown in FIG. 9). The user activates the heater of the aerosol generator so that the heater heats the aerosol-forming substrate as the user smokes on the article, thereby forming the aerosol. The heater may, for example, be continuously heated after initial activation by a switch triggered by the user's first smoke absorption or by a user-activated switch, or may be heated only when the user smokes an article. good. The formed aerosol is carried by the airflow into the user's mouth. The extraction tool 10 can be moved from the first operating position to the second extraction position when the aerosol-generating article is completely consumed or the user considers that the aerosol-generating article has been used up. This can be achieved manually by the user pulling on the mouthpiece 1. In that case, the user can grasp the mouthpiece 1 and pull the extraction tool 10 downstream from the heater casing 50. The extraction tool 10, and thus the mouthpiece 1, is configured such that the mouthpiece 1 is completely removed from the heater casing 50 if the extraction tool 10 is further pulled when it is in the second extraction position. This advantageously allows for the replacement and cleaning of the mouthpiece 1 and the extraction tool 10 as well as the cleaning of the heater casing 50 and the heater contained therein.

7a, 7b and 7c show that the elastic coupling element 25 is second when the extraction tool 10 is inserted into the heater casing 50 and when the mouthpiece 1 is reinserted after being removed from the aerosol generator. Shows how it is configured to engage the coupling opening 552. The protrusion 253 has a first inclined surface 254 oriented toward the first open end 21 of the extraction tool main body 20 and a second inclined surface oriented toward the second closed end 21 of the extraction tool main body 20. Includes an inclined surface 255 and the like.

The effective diameter of the extractor 10, defined by the maximum distance between the two opposing elastic coupling elements 25, is larger than the inner diameter defined by the heater casing 50. Therefore, when the extraction tool 10 is inserted into the heater casing 50, the second inclined surface 255 of the two elastic coupling elements 25 comes into contact with the inner edge of the heater casing wall defining the open end 51. The second inclined surface 255 is inclined sufficiently gently so that the advancement or sliding of the extraction tool 10 further upstream in the heater casing 50 causes the second inclined surface 255 to be the inner edge of the open end 51. And therefore the elastic coupling element 25 is displaced towards the body 20 of the extraction tool 10. As shown in FIG. 7b, deviating the elastic coupling element 25 towards the body 20 of the extractor 10 allows the extractor to frictionally engage with the inside of the heater casing 50. As the extractor 10 further slides within the heater casing 50, the protrusion 253 encounters a second coupling opening 552 at a distance away from the inner edge of the open end 51. The urging or elastic nature of the elastic coupling element 25 is that the protrusion 253 is detached from the extraction tool body 20 and detachably engaged with the second coupling opening 552, thereby moving the extraction tool 10 into the second extraction position. Position. The protrusion 253 effectively snaps into the second coupling opening 552. This is useful because the snap can provide the user with a tactile and audible indication that the extractor 10 has successfully engaged the second extraction position.

By further sliding the extractor 10 upstream along the heater casing 50, the second inclined surface 255 can be pressed against the upstream inner edge of the second opening 552 and thus again elastically coupled. The element 25 is displaced toward the main body 20 of the extraction tool 10. Similar to FIG. 7b, the deviation of the elastic coupling element 25 towards the body 20 of the extraction tool 10 heats the extraction tool at any position between the first coupling opening 551 and the second coupling opening 552. Allows frictional engagement with the inside of the casing 50. As the extractor 10 is further slid within the heater casing 50, the protrusion 253 is separated from the second coupling opening 552 and further away from the inner edge of the open end 51 by the first coupling opening. Encounter 551. The urging or elastic nature of the elastic coupling element 25 is that the protrusion 253 is detached from the extraction tool body 20 and detachably engaged with the first coupling opening 551, thereby bringing the extraction tool 10 into the first operating position. Join. The protrusion 253 effectively snaps to the first coupling opening 552. This is useful because the snap can provide the user with a tactile and audible indication that the extractor 10 has successfully engaged the first operating position.

When the extraction tool 10 is in the first operating position, the user can insert the aerosol-generating article into the extraction tool 10 so that heating and smoke absorption are possible. In some embodiments, further progress or sliding of the extractor 10 through the first operating position inside the heater casing 50 is with the closure surface 22 and flange 23 of the extractor body 20 and the heater casing 50. Not allowed due to contact with the inner surface supported within. However, the engagement of the elastic coupling element 25 with the first coupling opening 551 ensures that the extraction tool 10 is inoperably coupled to the heater casing 50 during operation of the aerosol generator and is withdrawn from the engagement. Only the intentional act of releasing the tool 10 ensures that the engagement is released.

As shown in FIGS. 7a, 7b and 7c, the second inclined surface 255 is inclined more gently than the first inclined surface 254, and the extraction tool 10 is further gradually slid into the heater casing 50. Ensure that the force required to move is less than the force required to pull the extractor from the second extraction position. It also means that a deliberate greater force from the user is required to completely remove the extractor 10 from the heater casing 50 or move the extractor 10 from the first position to the second position. to be certain. In other words, engaging the extractor 10 in the first and second positions is easier than disengaging the extractor 10 from the first and second positions, i.e., necessary. There is little power.

Sliding the extraction tool 10 from the first operating position to the second extraction position or completely removing the extraction tool 10 from the heater casing 50 involves a process similar to the engagement process described above. However, as described above, such disengagement movement requires a force in the downstream direction away from the heater rather than in the upstream direction toward the heater, and this requires the extraction tool 10 to be inserted into the heater casing 50. Sliding from the second opening 552 to the first opening 551 is involved. The main difference is that the first inclined surface 254 is the first coupling in order to offset the elastic coupling element 25 towards the body 20 of the extraction tool 10 and slide the extraction tool 10 downstream of the heater casing 50. It is a point pressed against the respective downstream inner edges of the opening 551 and the second coupling opening 552. As described above, since the first inclined surface 254 is inclined more gently than the second inclined surface 255, the force required to push the extraction tool 10 downstream of the heater is to heat the extraction tool 10. Greater than the force required to push upstream towards.

FIGS. 4, 5, 6a and 6b show an alternative second embodiment of the mouthpiece 1'and the extractor 10', which is attached to the extractor 10'of the second embodiment. The elastic coupling element 25'is mainly different from the first embodiment in that it is shorter in length than that of the first embodiment. In the first embodiment, the length of the elastic coupling element 25 is equal to or in between at least 50% to 100% of the length of the extraction tool body 20. In the second embodiment, the length of the elastic coupling element 25'is at least 50% of the length of the extraction tool body 20'. All other features mentioned above in connection with the first embodiment are present in the same embodiment in the second embodiment. Therefore, the features of the second embodiment, in which the reference numerals are omitted, can be considered to be substantially the same as those described with respect to the first embodiment of FIGS. 1, 2, 3a and 3b. The heater casing 50 configured to which the mouthpiece 1'of the second embodiment is coupled is substantially identical to that described above.

FIG. 8 shows the downstream end of the heater casing 50. The heater casing 50 has a protruding guide track 53 extending in the longitudinal direction along the inner surface of the heater casing 50. The guide track 53 is arranged so as to cooperate with a slot or groove (not shown) located on the outer surface of the extraction tool main body 20. The engagement of the guide track 53 with the corresponding slots on the extractor body 20 ensures that the extractor body 20 does not rotate and become inconsistent when positioned or slid within the heater casing 50. To.

FIG. 9 shows the mouthpiece 1 according to the present invention. The mouthpiece housing 30 houses the extraction tool 10 according to any one of the first embodiment and the second embodiment of the present invention described in detail above.
